I have seen you repeat this misinformation so many times, I have to respond with this. Maybe you ascribe to the notion "if you repeat a lie often enough, it is accepted".
Note everyone, this is an AoS developer saying that they had little async compute compared to what other developers are doing and getting.
Xpea claims the opposite, saying that AoS is the best case with 10% and the norm will be around 5%. Complete and utter misinformation repeated continually.
Oxide dev quote:
"Our use of Async Compute, however, pales with comparisons to some of the things which the console guys
are starting to do. Most of those havent made their way to the PC yet, but Ive heard of developers getting 30% GPU performance by using Async Compute."
Sony was instrumental in adding async compute to GCN way back when it was being designed. I wonder what is in store for the next Playstation PS5 model. For certain it's being worked on now.
